Dfea 2.1 Introduction To Solid Modeling - Review

An assembly file is a file that references and links to the individual parts files that make up the assembly. Without the parts files, the assembly file would not be able to locate and display the parts correctly. Therefore, if an assembly file is emailed to a friend without the parts files, it would not open correctly on the new computer.

The correct answer is "sketch (.sldskt)". This is because SolidWorks file types include parts (.sldprts), assemblies (.sldasm), and drawings (.slddrw), but "sketch" is not a recognized file type in SolidWorks. Sketches are created within parts or assemblies as a 2D outline or profile used to create features or geometry. However, they are not saved as separate file types themselves.

A model can be rotated using any of the given methods. The arrow keys can be used to rotate the model in different directions. Pressing and holding the middle mouse wheel allows the user to drag and rotate the model freely. Holding the shift key and using the arrow keys also enables the user to rotate the model. Therefore, all of the above options are valid ways to rotate a model.

Pressing the "F" key on the keyboard is the shortcut to "fit" a model to the screen. This means that when working with a model, pressing the "F" key will automatically adjust the zoom level or size of the model to fit the screen, allowing for a better view and easier navigation.

The correct answer is 1:2. This is indicated in the title block of the assembly drawing of the sterling engine. The scale of 1:2 means that every unit on the drawing represents two units in real life. This allows for a detailed and accurate representation of the engine's components and dimensions.

The correct answer is 6 because the question asks for the number of spacers on the lower cylinder. Since the answer choices range from 4 to 8, we can eliminate the options that are outside of this range. Therefore, the only option remaining is 6, which is the correct answer.

A solid model is defined by its volume, which refers to the amount of space it occupies in three dimensions. This means that a solid model is not defined solely by its exterior surfaces or wire frames, as these only represent the boundaries or structure of the model. Instead, the volume of the solid is what truly defines its shape and characteristics.

The statement is false because with the "Open Dialog window" in SolidWorks, users can not only open SolidWorks files but also files from other formats such as STEP, IGES, and STL. The Open Dialog window allows users to browse their computer for files and select the desired file to open in SolidWorks. This feature provides flexibility and compatibility for working with various file types in SolidWorks.

Hint: With the assembly open select the "propeller" and use the "in context menu" to open the propeller file. YOu can then find the description on the " custom properties" task pane.
